1. C. retorta, A. Cunn. ex D.C. Prodr. vi. 154.—A much or sparingly branched heath-like shrub 4–15 ft. high; branches stout, spreading, clothed with white tomentum. Leaves numerous, small, crowded, spreading and recurved, ⅛–⅕ in. long, linear-obovate or linear-oblong or oblong-obovate, obtuse, narrowed into a very short petiole, coriaceous, glabrous or hoary above, beneath clothed with dense white tomentum; margins recurved. Heads numerous, in small terminal corymbs, shortly pedicelled, turbinate, ¼ in. long; involucral bracts in several series; the outer shorter, ovate-oblong, tomentose; inner linear-oblong, with short white obtuse radiating tips. Receptacle with many white-tipped scales similar to the inner involucral bracts. Florets 6–20. Achenes glabrous, striate. Pappus-hairs slender.—Hook. f. Fl. Nov. Zel. i. 132; Handb. N.Z. Fl. 145; Kirk, Students Fl. 314.
North Island: Common as far south as the East Cape, usually near the coast, on sand-dunes, &c. November–February.
2. C. leptophylla, R. Br. in Trans. Linn. Soc. xii. (1817) 126.—Much like C. retorta in habit and general appearance, but branches more slender. Leaves smaller, crowded, erect or spreading or recurved, 112–18 in. long, narrow-linear or linear-spathulate, obtuse, coriaceous, glabrous above, clothed with white or yellowish tomentum beneath; margins recurved. Heads numerous, in small terminal corymbs, very shortly pedicelled, narrow-turbinate, a in. long; involucral bracts in several series; the outer broader and shorter, glabrous or nearly so; inner linear, obtuse, with short white radiating tips. Receptacle with white-tipped scales subtending the florets. Florets 6–12. Achene and pappus as in C. retorta.—A. Cunn. Precur. n. 447 (in part); Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 132; Handb. N.Z. Fl. 145; Kirk, Students' Fl. 314. C. spathulata, Col. in Trans. N.Z. Inst. xxii. (1890) 472. Calea leptophylla, Forst. Prodr. n. 287.
North and South Islands: Not uncommon from the East Cape southwards to Marlborough and Nelson. Tauhinu-korokio; Cottonwood. December–February.
Very close to the preceding, but differing in the more slender habit, smaller and narrower leaves, and smaller and narrower glabrate heads. Mr. Colenso's C. spathulata does not seem to me to be even entitled to varietal rank.
3. C. Vauvilliersii, Hook. f. Fl. Nov. Zel. i. 133.—An erect closely branched shrub 2–6 ft. high; branches stout, erect or spreading, often glutinous, grooved, and with the leaves beneath densely clothed with fulvous or whitish tomentum. Leaves numer-
